Would you change your amp selection knowing...?


OK - so this thread was promted by some comments on another thread - not wanting to hijack that thread I created this one...

ISSUE: some high current designed amps have an issue with speaker cables that have a high capacitance.
- the amp can be driven to self destruction because of internal oscilation caused by the high capacitance of the speaker cable
- this does NOT apply to Tube amps - i.e. to my knowledge

The amps I know of that are affected in this way are Ayre, Gryphon and NAIM
- only NAIM warns of this up front AND instruct their dealers to let customers know about it

So why don’t other brands warn about the possibility?

QUESTION:
- would it put you off?
- would you select a different amp if the manufacturer warned of this "issue" up front?

Cheers

 Thanks for starting this thread-I had no idea that this was a potential issue with my system!   I completely agree with @elizabeth  that it is both the amp and cable manufactures’ responsibility to warn the public if there is a potential issue with their product.

 Unfortunately, much of the electrical discussion I find to be extremely dense.  It would be a great service to the audio community if someone would provide a layman’s rule of thumb for determining whether their system may be  subject to harmful isolation to to  a poor match between amp and cables.
